摘　　要：用接触－冲击分析研究了复合材料层板线载荷冲击响应及损伤机理。分析中，考虑层板的材料性质、铺展顺序和长、宽、厚度等参数的影响。数值计算结果与实验结果完全符合。A contact-impact analysis is performed to study responses and damage mechanism oflaminated composites subjected to line-loading inpact. In the analysis, the effects of the parameters, such as material properties, stacking sequence, span or thickness of laminates havebeen taken into account. The numerical results agree with the expertrimented ones reasonablywell.
